Hi All,
I'm looking at how we can connect two pairs of Dave Clark headsets so that the wearer's can talk to each other. I'd also like to have an extermal mic that could be used to talk to both wearers and speaker outputing all comms on the system. Any ideas for hardware?. I was looking at something like this:

although I'm open to a more PC-based/USB solution. Any ideas?.

Ta in advnce,
Dave
